Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil composition for polyamide fibers.
The present invention relates to an oil composition intended to coat polyamide fibers.

Conventionally, polyamide fibers have the advantages of excellent mechanical properties and dyeability under normal pressure, and have been used in a wide range of fields such as interior products and automobile interior products in addition to general clothing. In general, polyamide fibers are made with acid dyes, except for dope dyeing (dope dyeing) for special purposes.

It is usually dyed with an anionic dye such as metal-containing dye VC. However, such dyeing has the following drawbacks. In other words, (1) the amount of staining (streak % (2) The anionic dye that has fallen off from the dyed product recontaminates the hot water (undyed area), which significantly deteriorates the appearance quality of the product.

Conventionally, in order to obtain level dyeing properties of polyamide fibers, thorough layering of θ near 1 was used to minimize fluctuations in the dyed seat amount, and the use of b1 + JC yarns and the use of i4 pairs of dyeing conditions (ηυ family with excellent level dyeing properties) use, PH control, addition of leveling agent, temperature increase speed control, etc.).

However, the disadvantages are that it takes a long time to separate the layers, that dyes with a quick level dyeing property have poor color fastness, and that P.T.
Methods such as i control, temperature increase speed control, and adding a leveling agent can achieve a certain degree of leveling effect from 4U to 7L, but they require a high level of control technology, require a long dyeing time, and are difficult to reproduce. It has drawbacks such as poor properties and is of little industrial utility. -Also, in order to prevent re-staining, there is a method of using a dye with a high wet fastness, and a method of fixing after thorough soaping, but it is important to note that the dye used is approximately It has drawbacks such as time-consuming process and lacks practicality.

As a result of intensive research into a method for leveling dyeing and preventing re-staining that does not have the above-mentioned drawbacks, the present inventors have discovered that level dyeing and re-staining prevention properties can be obtained by blending a specific treatment agent into the oil agent. Findings [-1] The oil composition of the present invention was achieved. That is, the present invention provides an oil agent for polyamide fibers characterized by containing an aromatic sulfonic acid condensate having at least one phenolic hydroxyl group and at least one sulfonic acid group in the molecule and an oil agent. It is a composition.

Examples of the aromatic sulfonic acid condensate having at least one phenolic hydroxyl group and at least one sulfonic acid group in the molecule used in the present invention include syntanes. Specific examples include formaldehyde condensates of phenolsulfonic acid, methanesulfonic acid as novolac type resins, methanesulfonic acid as resol type resins, and resins obtained by condensing phenols tonaphthalenesulfonic acid with formaldehyde. In particular, the following general formula (1)

It is one of the factors that greatly affects the re-staining prevention effect of acid dyes and total dyes.
- For polyamide fibers, it is preferable to use a compound whose affinity is smaller than that of the dye used, and for prevention of red staining, it is preferable to use a compound whose affinity is larger than that of the dye used. The compound may be used in combination with two or more glazes.

Swelling agents optionally combined with aromatic sulfone compounds include monohydric alcohols such as butyl alcohol, ethylene glycol, polyalcohols and their modified forms, phenylphenol, Methyl benzoate, methyl salicylate, 7-tal diethyl,
Examples include aromatic compounds such as phenolsulfonic acid and benzyl alcohol, but alcohol-based compounds are preferred.
Of these, benzyl alcohol is particularly preferred.

When the ester leveling agent is not used at all, it is preferable to add a swelling agent.

“Furthermore, the oil agents that can be blended include, for example, spinning, stretching,
In order to maintain the productivity and performance of lj74% processing and other post-processes, requirements include lubricity, antistatic properties, focusing properties, and heat resistance to withstand thermal decomposition on the heater! Satisfy the characteristics [Must be 7. Examples of substances that meet these required properties include -basic acid esters +11, dibasic acid esters, polybasic acid esters, and tallicol esters I'b (,
Examples include ester smoothing agents such as polyhydric alcohol esters, but fatty acids (i+) and (m) = dialkyl ester of basic acid; preferred examples include dipropyl sebacate, dilauryl sebacate, and dilauryl adipate. Examples include. The ester leveling agent also functions as a swelling agent for polyamide. Also, as an oil agent, mineral oil,
Liquid oils such as silicone oil can also be used, and among these, high viscosity mineral oil is preferred. It is particularly preferable to use the above ester-based lubricant in combination with a liquid oil agent. Argylene oxide adducts, pluronic type activators, and the like are used in the l- for use.

In addition, the ratio of the ester smoothing agent and the liquid oil agent in the oil agent component is preferably 15-80:85-20 M, and the 'lit ratio is l-'y'h.

The oil composition of the present invention is applied to polyamide-based fibers or threads, especially undrawn fibers, by known methods such as rolling, dipping, and spraying. It is suitable to use it as

Polyamide fibers used for swords and a include wool, silk, and P.
Natural polyamide fibers such as
N6, Nylon 616, Nylon 11, Nylon 12,
Good results can be obtained when applied to synthetic polyamide fibers such as aromatic nylon, protein/acrylonitrile copolymer fibers, and the like.

The aromatic sulfonic acid condensate in the present invention improves the level dyeing property and re-staining prevention property, but the ester-based smooth j+lI' mafc can be applied in combination with the aromatic sulfonic acid condensate to the inside of the fiber. This facilitates the penetration of the dye, giving an excellent level dyeing effect. Swelling agent 1 (i±) can also promote internal penetration of the oil agent.

[, Therefore, J′ treated with the oil composition of the present invention
L7c polyamide fiber has improved spinning drawability and post-process passability, good abrasion resistance, excellent level dyeing properties, and stain resistance, and can be processed without requiring pretreatment such as fine graining. , excellent level dyeing properties can be obtained even when dyed as is and for a short period of time, contamination of hot water during soaping after printing is prevented, 1F is effective when washing and wearing mixed knitted fabrics of dyed and undyed yarns. It has many features such as no contamination of undyed yarn by dye that bleeds out, and the ability to obtain a d-light effect even when using a single dye by mixing it with fibers treated with aromatic sulfonic acid condensate additive-free oil agents. ing.

Although it is unclear why the oil composition of the present invention provides excellent level dyeing properties and redeposition prevention properties, it is unclear why the oil composition of the present invention provides excellent level dyeing properties and re-staining prevention properties. By using IJ with a swelling agent, an anionic compound can be applied evenly to the inside of the fiber coating layer, and evenly applied to each fiber.
This is thought to be due to the fact that the anionic compound and the dye used (anionic dye) have an effect of preventing recontamination of evenly dyed young fruits depending on the affinity for fiber PC.

The oil composition of the present invention may further contain fluorescent dyes, flavoring dyes, fungicides, ultraviolet absorbers, etc., if desired.
It's also possible.

In addition, as a leveling agent for polyamide, it is suitable for dyes.
('i-(, -) Although it is possible to use a cationic compound having -, it has problems such as compatibility with the spinning oil, complex formation with the dye during dyeing, and discoloration.
Therefore, it is inappropriate.
